Hi Peter, I also, on upgrading to Lion, took the opportunity to shed a lot of the cruft that I had accumulated over the years. It is also a great opportunity to make sure that applications that run in the background are only ported across if absolutely necessary. Having said that I think Option 2 is your best bet -- I will even offer a modification to it since I have sworn off large chunks of plastic with low data density that go by the name of DVD.
You could : 1) Download the Lion OS X 10.7 app from the App Store to your current OS X10.6 install. 2) Make one last copy of your 10.6 install to an external drive so you can be sure you have missed nothing. 3) Boot from the external drive with running 10.6 and run disk utility to erase your internal drive 4) Run the Lion install app from you external drive and install an unmodified copy of Lion to your internal drive. You can then proceed to port the data and accounts across. I am just on my way out but others can post on the data porting or I will write again when I get back.
